Let’s learn “Shell Scripting". So, in this post I wanted to talk about “What is a shell script?" & "learner guide to shell scripting with examples". Before jumping into learning on how to code and execute shell scripts, let’s talk a bit about “Linux” and history of Linux.

Linux is technically the kernel, so, there are other utilities such as GNU tools, GCC compiler etc,. which would ideally make a complete operating system (OS). That is the reason it is called GNU (GNUs not Unix) Linux not simply Linux. Ideally one must say 'GNU Linux' not just 'Linux'. GNU Linux is one of the widely used OS in market, because it is open-source, so anyone could download/re-use the kernel, publish a new Linux distribution under the guidelines of GPL & Free Software Foundation.

We could use “if” statement when it is required to perform a conditional based operation. So, if the condition is true then process a set of commands, otherwise, process some other commands/action. The syntax of this is:

About Me.

This is just about me, my experience, my interest, my passion.... I am from Mysuru which is so popularly known as Cultural Capital of Karnataka(India). I started my carrier as a technical support person, my interest grew on Linux, started working on Linux operating system, currently working as Infrastructure Lead in a private company. Although I got enough experience in this Linux world I still feel there is some empty space which needs to be filled up every day, so, every day there is a new learning, that is what we say, learning is a never ending path. We are all here to share/learn/spread the knowledge. There is much more to learn/gain in this open-source world. Happy Learning.....
